1-3 Chipset Overview

Built upon the functionality and the capability of the Intel 5500 Series Processor

and the 5520 chipset, the X8DTH-6/X8DTH-6F/X8DTH-i/X8DTH-iF motherboard

provides the performance and feature set required for dual-processor-based

high-end systems optimized for High Performance Computing (HPC)/Clustering

severs. The Intel 5520 chipset consists of dual 5520 IO hubs, and an ICH10R

(South Bridge). With the Intel QuickPath Interconnect (QPI) controller built in, the

Intel 5500 Series Processor is the ﬁ rst dual-processing platform to offer the next

generation point-to-point system interconnect interface to replace the current

Front Side Bus Technology, substantially enhancing system performance and

scalability.

The 5520 IO Hub connects to each processor through an independent QPI link.

Each link consists of 20 pairs of unidirectional differential lanes for transmission

and receiving in addition to a differential forwarded clock. A full-width QPI link

pair provides 84 signals.

The Intel 5520 supports up to 36 PCI Express Gen2 lanes, peer-to-peer read and

write transactions. The ICH10R provides up to seven PCI-Express ports, six SATA

ports and seven USB connections.

In addition, the Intel 5520 chipset also offers a wide range of RAS (Reliability,

Availability and Serviceability) features. These features include memory interface

ECC, x4/x8 Single Device Data Correction (SDDC), Cyclic Redundancy Check

(CRC), parity protection, out-of-band register access via SMBus, memory mirror-

ing, memory sparing, and Hot-plug support on the PCI-Express Interface.

1-4 Special Features

Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond when

AC power is lost and then restored to the system. You can choose for the system

to remain powered off (in which case you must hit the power switch to turn it back

on) or for it to automatically return to a power- on state. See the Advanced BIOS

Setup section to change this setting. The default setting is Last State.

1-5 PC Health Monitoring

This section describes the PC health monitoring features of the X8DTH-6/X8DTH-

6F/X8DTH-i/X8DTH-iF. All have an onboard System Hardware Monitor chip that

supports PC health monitoring. An onboard voltage monitor will scan these onboard

voltages continuously: CPU1 Vcore, CPU2 Vcore, CPU1 Vtt, CPU2 Vtt, CPU1

DIMM, CPU2 DIMM, 1.1V, 1.5V, 1.8V, 3.3V, 12V, 5V, 3.3 Vsb, and VBAT. Once a

voltage becomes unstable, a warning is given or an error message is sent to the

screen. the user can adjust the voltage thresholds to deﬁ ne the sensitivity of the

voltage monitor.

Fan Status Monitor with Firmware Control

The PC health monitor can check the RPM status of the cooling fans. The onboard

CPU and chassis fans are controlled by Thermal Management via BIOS (under

Hardware Monitoring in the Advanced Setting).

Environmental Temperature Control

The thermal control sensor monitors the CPU temperature in real time and will turn

on the thermal control fan whenever the CPU temperature exceeds a user-deﬁ ned

threshold. The overheat circuitry runs independently from the CPU. Once it detects

that the CPU temperature is too high, it will automatically turn on the thermal fan

control to prevent any overheat damage to the CPU. The onboard chassis thermal

circuitry can monitor the overall system temperature and alert users when the chas-

sis temperature is too high.

Warning! To avoid system overheating, be sure to provide adequate air

ﬂ ow to the system.

System Resource Alert

This feature is available when used with Supero Doctor III in the Windows OS

environment or used with Supero Doctor II in Linux. Supero Doctor is used to

notify the user of certain system events. For example, you can also conﬁ gure

Supero Doctor to provide you with warnings when the system temperature, CPU

temperatures, voltages and fan speeds go beyond a pre-deﬁ ned range.

1-6 ACPI Features

ACPI stands for Advanced Conﬁ guration and Power Interface. The ACPI speciﬁ ca-

tion deﬁ nes a ﬂ exible and abstract hardware interface that provides a standard

way to integrate power management features throughout a PC system, including

its hardware, operating system and application software. This enables the system

to automatically turn on and off peripherals such as CD-ROMs, network cards, hard

disk drives and printers.

In addition to enabling operating system-directed power management, ACPI

provides a generic system event mechanism for Plug and Play and an operating

system-independent interface for conﬁ guration control. ACPI leverages the Plug

and Play BIOS data structures while providing a processor architecture-independent

implementation that is compatible with both Windows 2000 and Windows 2003

Operating Systems.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking

to indicate that the CPU is in suspend mode. When the user presses any key, the

CPU will wake-up and the LED will automatically stop blinking and remain on.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a system

suspend button to make the system enter a SoftOff state. The monitor will be

suspended and the hard drive will spin down. Pressing the power button again

will cause the whole system to wake-up. During the SoftOff state, the ATX power

supply provides power to keep the required circuitry in the system "alive." In case

the system malfunctions and you want to turn off the power, just press and hold

the power button for 4 seconds. This option can be set in the Power section of the

BIOS Setup routine.

1-7 Power Supply

As with all computer products, a stable power source is necessary for proper and

reliable operation. It is even more important for processors that have high CPU

clock rates.

X8DTH-6/X8DTH-6F/X8DTH-i/X8DTH-iF User's Manual

The X8DTH-6/X8DTH-6F/X8DTH-i/X8DTH-iF can accommodate 24-pin ATX power

supplies. Although most power supplies generally meet the speciﬁ cations required

by the CPU, some are inadequate. In addition, the two 12V 8-pin power connections

are also required to ensure adequate power supply to the system. Also your power

supply must supply 1.5A for the Ethernet ports.

Warning: To prevent damage to the power supply or motherboard, please

use a power supply that contains a 24-pin and two 8-pin power connectors.

Be sure to connect these connectors to the 24-pin (JPW1) and the two

8-pin (JPW2,JPW3) power connectors on the motherboard for adequate

power supply to your system. Failure in doing so will void the manufacturer

warranty on your power supply and motherboard.

It is strongly recommended that you use a high quality power supply that meets ATX

power supply Speciﬁ cation 2.02 or above. It must also be SSI compliant (For more

information, please refer to the website at http://www.ssiforum.org/). Additionally, in

areas where noisy power transmission is present, you may choose to install a line

ﬁ lter to shield the computer from noise. It is recommended that you also install a

power surge protector to help avoid problems caused by power surges.

1-8 Super I/O

The Super I/O supports 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data

transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s. It also provides two high-speed,

16550 compatible serial communication ports (UARTs). Each UART includes a 16-

byte send/receive FIFO, a programmable baud rate generator, complete modem

control capability and a processor interrupt system. Both UARTs provide legacy

speed with baud rate of up to 115.2 Kbps as well as an advanced speed with baud

rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.

The Super I/O provides functions that comply with ACPI (Advanced Conﬁ guration

and Power Interface), which includes support of legacy and ACPI power manage-

ment through an SMI or SCI function pin. It also features auto power management

to reduce power consumption.
